In an hour, the printing press will produce \(\frac{60t}{m}\) books. 'n' printing presses would produce \(\frac{60nt}{m}\) books per hour. In order to product 10000 books, the presses will need \(\frac{10000m}{60nt}\) hours (Option D)

Assuming numbers

1 printing press will produce (t = 10) books in (m = 6) minutes.Therefore, 1 printing press produces \(\frac{5}{3}\) books in a minute. In an hour, the printing presses will produce \(60(\frac{5}{3}) = 100\) books.If there are (n=10) machines to do the work, every hour 1000 books are printed

In order to print 10000 books, it took the n printing presses \(\frac{10000}{1000} = 10\) hours.
